Subject: v24i039: Email fax-sending package, Part01/05 Newsgroups: comp.sources.unix Approved: rsalz@uunet.UU.NET X-Checksum-Snefru: 0c8fe16e 6f072551 39bbea94 42baa701 Submitted-by: klaus u schallhorn <cnix!klaus> Posting-number: Volume 24, Issue 39 Archive-name: faxpax/part01 This is faxpak [Copyright (C) 1991 klaus schallhorn, klaus@cnix.uucp] faxpak currently runs on Suns only - not because it uses any spe- cial SunOs features, but because I don't have access to anything else. I developed faxpak mainly on a 4/60, then moved it to a 3/60 that does all our spooling. Apart from [temporary] hardware and typeface restrictions [see below] faxpak is quite flexible. It allows faxes to be sent from any networked machine. It allows aliases and distribution lists. Entries in such lists needing a special "for the attention of" string are forked out as separate jobs. If you have more than 1 fax modem, faxpak automatically shares the load between these modems. This includes splitting of batches to distribution lists into several queues. faxpak enforces permissions. You can set faxpak up to send local faxes any time, long distance ones and international ones to be sent at cheap rates only. You can enforce the sending of faxes to any given phone number at fixed times. And you can permit some users to override these time restrictions. faxpak was created when the post office increased our contract postage rates to an almost insane level. We therefore decided [as a small publishing house] to deliver our newsletter by other means. We now deliver by mail(1) to subscribers' mailboxes at various online and video text systems, we allow direct modem con- nection to mbox [our 3/60] and we fax our newsletter. faxpak is used for oneoff faxes [and only if I can't email], and has been used three times [we publish every other week] for batches of ~150 faxes @ five pages each to our subscriber list. Batches of this size take a good two nights to send out, although the pure transmission time is just under 12 hours [the rest is engaged phone lines, repeats because transmission errors, logins sneaking in on the faxmodems, etc]. faxpak currently supports touchbase's 2496 fax modem and others that use or emulate the sierra type fax chipset, such as zoom's mx 2400s. Early december I found someone willing and supposedly able to ship a beta class2 modem. Unfortunately it seems to have been sent by bicycle. It's supposed to be here "real soon now". For this reason faxpak does [not yet] support other modems, nor does it allow incoming faxes. #! /bin/sh # This is a shell archive.

X X This software is provided "as is" without express or implied warranty. X X X faxpak is late by about 6 weeks. It turned out that the way X the faxmodem communicates with the host is extremely, well, X artistic. It also turned out that g3 files, as specified X in the ccitt specs need quite a bit of processing before X they can be stashed down the serial port. X X The faxmodem basically makes the assumption it's running X on a medium to fast dos box. It assumes it has the undivided X attention of the host, and it assumes it can fiddle with X the actual wiring between the host and the modem at will X [like the guy in the movie trying to start a stolen car]. X X If, for instance, you're using hardware flow ctl, the X fax modem still sends tons of xon's/xoff's although you X specified NOT to use xonoff. X X pauses of more than one fifteenth of a second during the X tx [transmission] phase of a fax result in a quiet abort. X The faxmodem regards this as "end of page" and squirts X abuse to the fax machine at the other end. X X Imagine news expiring a full feed, or processing an incoming X batch, and the standard cron tab entry finding old garbage X and removing it and you can see that a delay of something X like 60 or 70 milliseconds is quite possible. X X I therefore suggest not to schedule any faxes at or X around the time disk intensive cron jobs are due if you cannot X guarantee there won't be any major swapping. X X A 3/60 handles concurrent "find", or "newsrun" and faxes ok. X Copying a few Mb via nfs while your sending multiple faxes works X as well. X X On a 10 mhz 286 [dos] box printf statements while transmitting X can screw you up [actually not you, but the outgoing fax]. X They take too long. And I'm not kidding. X X I assume "Flow control" is done partly in rs232 fashion, X more so according to what's possible and common on dos boxes. X In fact, the various modem manufacturers' specs specify which X bit in which register to twiddle, in the dos box hardware, X rather than how to connect to a serial port. X X This proves to have no effect - unless the fax modem is X actually connected to a dos box. X X In the course of getting this to work I have used three rolls X of fax paper, resorted to beating the fax modem [makes you X feel real good. Doesn't advance the issue though], and missed some X of my favourite tv pgms. X X After some persistant phone calls to the vendor I even X discovered that my modem had beta release firmware [no hint of that X in the sales blurb or the tech specs]. A "pre release" prom was X promised and arrived promptly after a week [I actually got two]. X Clearly labelled "BETA RELEASE" this time. I would X not be surprised to find further discrepancies between specs X and real life [incorporated into the wiring, 26.1.90]. X X Well, at least it works now, on Sun 3's and Sun 4's [I run 4.1], X using hardware flow ctl - no chance with xon/xoff. X X If you don't have a Sun, and cannot yet get your hands on one X of these "available real soon now" class2 modems [I'm still waiting], X I suggest you get a fax modem X X ON LOAN, or X ======= X ON APPROVAL, X =========== X X and have the supplier [remember, it's not a vendor yet] confirm X that the modem's command set adheres strictly to the CCITT T.30 X specifications [dubbed sierra], as outlined in the enclosed X document "writefax.man" which I picked up on the net. X X There are faxmodems out and available now that currently X support T.30 *and* some proprietary command set [often using X a binary language when analysed with a serial port sniffer]. X Some faxmodems come with a non standard command set and need X an upgrade in firmware to make them t.30 compatible [like the X ones I used]. Others will be relaunched as t.30 compatible ones, X again, "real soon now" [honestly, I'm running beta]. X X You have to make sure though that the modem recognises AT LEAST X the sierra, or t.30, standard - class2 type modems of course X would be far better, but as far as I know the standard is still X in the making. The making of the modems thusly might take just X that little bit extra. X X I'm not trying to discourage you. X X I just want to make sure you don't run out and buy yourself X a fax modem you can only use with the vendors software on a dos X box [why don't you use email anyway?]. X X Only after you've aquired a fax modem on the terms outlined X here should you play with this module with: X X#define TESTING X#define TEST_DEVICE=\"/dev/whatever_device_is_handy_for_testing\" X X to get it working. And only if you get it to work on your system, X is faxpak a make, install 'n run package. X X During development it's certainly helpful to turn incoming X getty's OFF. Otherwise you might have to reboot because X an aborted attempt might block the port from further use. X X If the modem works to your satisfaction for several years X you may pay the bill for the modem. X X It is possible that I have to port this within the next six to X eight weeks to a xenix 286 box - a system I know nothing of. X But I won't know this for sure until early march.

X X Testing on a dos box showed that by delaying the digesting of a X received xoff by two bytes screwed up the fax.
